ABB Phase Monitoring Relay, 3 Phase, DPDT, DIN Rail - 1SVR730774R1300 CM-PAS.31S

CM-PAS Three-Phase Monitoring Relays. The CM-PAS.x1 are monitoring relays for three-phase mains. They monitor the phase parameters phase sequence, phase failure and phase unbalance. The threshold value for phase unbalance is adjustable. Monitoring of three-phase mains for phase sequence, phase failure, phase unbalance Threshold value for phase unbalance adjustable as absolute value Tripping delay can be adjusted or switched off by means of a logarithmic scale ON-delayed tripping delay Powered by the measuring circuit True RMS measuring principle 2 c/o (SPDT) contacts 3 LEDs for status indication
